COMBINED BURGLAR-ALARIVI AND LCK.

SPECIFICATION forming part of Letters Patent No. 605,344, dated June 7,1898.`

Application filed `January S, l 8 9 8.

T0 all whom; t may concern:

Be it known that. I, GHAUNCEY R. SABIN, a citizen of the United States,`residing at the city of St. Louis, in the State of Missouri,

' have invented a certain new and useful Improvement ina Combined Burglar-Alarm and Lock, of Which'the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this Specification.

My invention relates to that class of devices in which a burglar-alarm'is combined in connection with a Window or door lock in such a manner that any 4unauthorized attempt to break into a building by a-burglar causes the alarm to be operated and Warn" the occupants of the building` of the attempt to gainaccess to the building through a Window or door. The device combines an` alarm-box containing an explosive-cartridge-receiving-receptacle, a locking-bolt anda trigger, and operating mechanism whereby the opening of the Window oridoor causes the trigger and operating mechanism to be actuated and the cartridge in the alarm to be exploded. The locking-bolt enters a recess in the alarm-box and is so arranged that after the alarm has been" actuated and the Warning furnished the WindoW or door `remains Ain a locked condition.

Myinvention consistsin features of novelty hereinafterfully described, and pointed out in the claims. y

Figure I is a front elevation. of the alarm and lock. Fig. II is a vertical sectional view taken on line II II, Fig. III. Fig. III is a top view. Fig. IV is a vertical cross-sectional view taken on line IV IV, Fig. III. Fig. V

is a front elevation of the alarm portion 'of the device, illustrating the position ofthe parts as assumed in the act of tripping the alarm. Fig. VI is a `top view of the alarm portion of the device, Showing the cartridgeexploding member swung out of contact With the cartridge into the position assumed when the cartridge is inserted or an exploded shell is to be removed. .A

As illustrated, 1=-designates the meetingrail of the lower sash of a Window, and'2 the meeting-rail ofthe upper sash.

3 designatesthe alarm-box, which is proseri'dl no. acacia. 'tno model.)

videdivith extending arms 4,containing openings byvvhich the box is secured tothe meeting-rail of the upper sash `by screws 5 or other suitable means offastening. In one side of the box 3 is a recess 6, that receives the lock- 55 ing-bolt when the sashes are fastened.

7 designates a bore extending from the bottom of the alarm-box to a point near its upper end. In this bore is a slidable bolt V8, Whose upper end extends through the upper 6o end of the box 3 and is provided With an arm 9,`the end of which is formed into a fingerpiece 10. On the under side of the arm 9 is a firing-pin 11, and on the side of the bolt 8 is a stud 12.- The bolt 8 within the bore 7 is 65 surrounded by a spring 13, that bears against the upper end of the bore, and the lowerend of which spring bears against a Washer 14,

held from displacement by a pin 15, passing throughthe bolt. In the upper end of the -7'0 box 3 is a receptacle 16, that is designed to receive an explosive cartridge A, as Shown. Leading from the receptacle 16 is an outletchannel 17 for the discharge of the resultant products of explosion on the firing of the cartridge.j In the side of thel box 3 is a groove 1 8, and'on the arm 9 of the bolt Sis aguidepin that is arrangedto play in the groove 18 for the purpose of limiting the inward swingof thearm 9 and guide the firing-pin l1 in 8o proper direction onto the head of the cartridge.

2O is a trigger Vpivoted to'thebox 3 at 21. The free end of this trigger is adapted tohcontact With the stud 12, said free end prefer- 85 ably having a curved edge that contacts With the stud 12 in order that the trigger Will travelmore easily in contact With said stud. 22 designates a bolt-bracket that receives a bon-f2s, provided with d handle 2r. The 90V bracket 22is secured to the Window-sash opposing that upon `which the alarm-box is carried, and the inner end of the bolt 23 is adaptned to enter the recess 6 of said alarm-box, and

when in position ready for operation. of the alarm and for locking the Window-sash the bolt is arranged beneath the'triggerO, as is clearly shown in Figs.` I and IV. T

The recess extendsto a sufcientheight above the locking-bolt-contacting ed'gelof the roo the locking-bolt 23`may be thrown into the of my improved burglar-alarm and lock:`

When it is desired to set the alarm, the arm 9 of the bolt 8 is grasped by the finger-piece 1() and swung into the position shown in Fig. VI, it being understood that the trigger 2O has been previously swung out of line of travel of the arm 9 and the parts carried by it by throwing it over past said arm to a greater extent than that illustrated in dotted lines in Fig. V. The cartridge is then inserted in the receptacle 1G. The trigger 2O is then thrown back into the position shown n in Fig. I, and the arm 9 being swung back over said cartridge the firing-pin will rest upon the cap of the cartridge, the guide-pin 9 will rest in the groove 1S, and the stud 12 Will be in a position immediately above the free end of the trigger 20. lVith the parts in the positions described the spring 13 holds the bolt S in an inward position and the iirin g-pin 11 is held in contact with the cartridge A. The parts being arranged as described,

recess 6 or retracted therefrom at will by manipulating the bolt through means of its handle 24. When the locking-bolt 23 is thrown into the recess 6 beneath the trigger 20, the window is locked, and unless the boltf is retracted neither window -sash can be opened farther than the limit of the recess G,

. tion, acting against the spring 13 and contracting it. lVhen the point of the trigger 2O reaches the stud 12, the firing-pin 11 has been removed from the cartridge A to a considerable distance, and as the movement of the trigger 20 continues said trigger is thrown past the stud 12, as illustrated by dotted lines, Fig. V, and the expansion of the spring 13 causes the return movement of the bolt 8, in which action the firing-pin 11 is brought suddenly into impact with the cartridge and the cartridge is exploded, thereby furnishing an alarm to the occupants of the building of an attempt to open the window.

lVhen a fresh cartridge is to be inserted, the parts are manipulated as before described in regard to the insertion of a cartridge, and the shell of the exploded cartridge is removed and a fresh one inserted in its place.

In speaking of cartridges herein it will be understood that it is the intention to employ what are known as blank cartridges,which contain an explosive, but do not contain a projectile. I

While I have shown and described in detail the device herein set forth as applied to a window, it is obvious that it is equally applicable to use in connection with a door, as the alarm-box in such instance would be attached to the door-frames, and the lockingbolt would be attached to the door.

I'clai-m as my invention- 1. A burglar-alarm and lock comprising an alarm-box provided with a cartridge-receptacle, a locking-bolt adapted to be thrown into said alarm-box, a spring-controlled bolt having an arm and located in said box and normally retracted by said spring, a firing-pin carried by said arm, and a trigger carried by said box, adapted to bear on said locking-bolt and on said spring-controlled bolt and trip the latter,.substantially as described.

2. A burglar-alarm and lock comprising an alarm-box provided with a cartridge-receptacle, a locking-bolt adapted to be thrown into said alarm-box, a spring-controlled bolt having an arm and located in said box and normally retracted by said spring, a firing-pin carried by said arm, a stud carried by said bolt, and a trigger carried by said box adapted to bear on said locking-bolt and on said stud and to trip said spring-controlled bolt, substantially as described.

3. A burglar-alarm and lock comprising an alarm-box provided with a cartridge-receptacle and containing a recess in one of its sides, a locking-bolt adapted to enter said recess, a spring-controlled bolt having an arm and located in said box and normally retracted by said spring, aV firing-pin carried by said arm, a guide-pin carried -by said arm, and a trigger carried by said box and adapted to bear on said locking-bolt and on said 'spring-controlled bolt and trip the latter, substantially as described.

4. A burglar-alarm and lock comprising an IIO alarm-box containing a cartridge-receptacle,
